Lollapalooza got slammed on social media just minutes after posting its 2018 lineup once fans realized the event was sorely lacking female headliners.

The annual Chicago music festival’s announcement on Wednesday boasted Bruno Mars, The Weeknd, Jack White and Arctic Monkeys as its most popular headlining acts. It wasn’t until the fourth line of the festival announcement poster that a female artist was even mentioned — CHVRCHES, St. Vincent and Dua Lipa were among the first women to grace the poster.

Fans were quick to point out the festival’s unfair representation of women.

“Wow, it’s like they didn’t know any female musicians big enough in the world to headline …” one Twitter user wrote.

“#Lolla out here with no female artists in its top three lines of artists like they don’t know what century it is,” another added.

Travis Scott was listed fifth on the line-up for the event taking place Aug. 2 to 5, while St. Vincent was written considerably smaller in the fourth row.

“How does the first female act not come until the 4th line? ALL HEADLINERS and 3 lines of all dudes?? St. Vincent at the least should of been higher,” another Twitter user questioned. “Do better.”

There were more than 80 artists on the poster and only 18 were female.

In past years, Lolla, which was first started in 1991, headlined with mostly males. In 2016, Grimes, the singer-songwriter whose real name Claire Elise Boucher, was the first female headliner listed on that year’s poster, but she wasn’t mentioned until the third line. Florence and the Machine was mentioned third on the 2015 line-up, and the next female artist, Marina and the Diamonds, wasn’t mentioned until several lines later.

The 2018 Coachella festival takes a slightly different approach.

Beyonce stands as its sole female headliner, though other women — including SZA, St. Vincent, Haim and Cardi B — are higher up on the bill.

New York’s Governor’s Ball in June has similar headliners: Jack White, Travis Scott and Eminem, but directly under the big names are female acts like Yeah Yeah Yeahs, Halsey, Sylvan Esso and CHVRCHES.

Lollapalooza did not immediately respond to a Daily News request inquiring about the lack of female headliners or asking if Lorde was offered a slot at this summer’s festival.

On March 11, Cody ran the Modesto Marathon while pushing her 15-month-old triplets in a 4-foot-wide stroller (total weight: 120 pounds), finishing the 26.2 mile course in 4:06:33. She beat her own record, having completed a similar feat in the Fresno Half Marathon.

Cody took on the task in an effort to raise money and awareness for the El Camino Hospital Neonatal Intensive Care Unit, where her triplets, who were born seven weeks early, received care.
